RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application No.60/774,941, entitled “SYSTEM AND METHOD FOR TROLLING,” filed Feb. 17,2006, the entirety of which is hereby included by reference.

TECHNICAL FIELD

The embodiments described herein are generally directed to fishingequipment, and more particularly to fishing tackle.

BACKGROUND

Fishermen typically use trolling techniques on bodies of water to catchfish. One method of trolling includes running multiple lines from theback of the boat. To provide a life-like “action” to a fishing tacklecomponent (in one example a lure), a fisherman would “pump” the lure bymoving the rod in and out such that the lure would rise and fall in thewater at periodic intervals. This “jigging” action is known to attractfish to lures. However, a rear-dragging line method is prone to tanglingof lures when more than one rod is in use. Further, if a fisherman wereto “pump” the lures, another fisherman would have to be in control ofthe boat. Additionally, where multiple rods and lures are used, afisherman may be disenchanted with the necessity of continuouslychanging rods in order to “pump” each lure.

To solve the problems of line-tangling with rear-dragging lures, planerboards have begun to enter the sport-fishing arena as a method toimprove fishing success. Planer boards are typically buoyant plastic orwooden structures that are pulled behind or along side a boat. The mostcommon planer board is a plastic side-planer that maintains apredetermined distance from either side of the boat, as determined bythe fishermen. When using planer boards, multiple lines may be pulledbehind the boat and, because they are positioned at various distances,they are not prone to interference or tangling with each other's lines.Thus, the use of planer boards is more efficient than using a singlefishing line or a rear-dragging setup.

When fishing, the planer boards are positioned behind the boat, or onthe sides of the boat, and a trolling speed is determined. A typicaltrolling speed is between one half (½) mile per hour and two (2) milesper hour, depending on water conditions. When setting up and deployingthe planer boards, a higher speed may be used to increase the line feedrate in order to reduce the deployment time of the planer boards (i.e.,when a faster speed is used the line is let out more rapidly). Four ormore planer boards may be used to increase the number of lines in thewater and to increase the chances for fish strikes. A fisherman may alsouse downriggers along with the planer boards to maximize fishingopportunities.

When using multiple planer boards (typically side planer boards)fishermen adjust trolling methods in an attempt to make the lures moreenticing to the fish. One method using planer boards is to turn the boatperiodically so that the lure behaves in a more life-like manner. Byturning the boat, generally using a constant series of S-turns or zigzagmotions, the lure will slow momentarily at the beginning of a turn andthen speed up as the line tension increases through the turn. Thismethod provides the lure with a life-like “action” in that live baitdoes not move through the water with steady-state motion. By providing“action” to the lure, or periodic changes in movement of the lure, afish is more likely to attack the lure. Thus, the “action” provides morestrikes than simply trolling in a straight line at a constant speed.However, the turning method requires the constant attention of the boatoperator/fisherman to perform the turns. Thus, the fisherman is lesslikely to see a “strike” because he is concentrating on the turns ratherthan watching the planer boards for a strike indication. When thefisherman is distracted, a fish has a greater chance of escaping thelure's hook.

Another method of providing “action” to bait is to operate the boat'sthrottle such that the boat slows and speeds up periodically. Thismethod may also be performed by taking the boat in and out of gear.Using the variable boat-speed method, the lure or bait will slow downand increase speed periodically along with the boat. This method,however, increases wear and tear on the propulsion systems of the boat.By constantly adjusting speed, the throttle linkages, as well as themotor mechanisms are under constant changes in conditions that increasestress on the components.

In use, the boat-turning and throttling method require a great amount ofattention of the boat operator. Additionally, even the most attentiveboat operator cannot provide for consistent “action” of the lure. Thus,the lure will not be consistently moving in a periodic fashion. Thisinconsistency leads to the inability to fine tune the lure's action forthe fishing conditions at hand. For example, when fishing in atournament, a fisherman may attempt to determine the optimum conditionsfor the lure's action early on in the tournament, or during practice.When the tournament begins, the fisherman may adjust the operation ofthe boat with the throttle or turning to tune the boat movements to thefishing conditions. In the trial and error period, the fishingconditions may include water temperature, weather conditions, boat andwater speed, clarity of the water, depth of the water, and, of course,the type of fish sought. Additional considerations for the operation ofthe planer board include the lure type, color, size, and desiredrunning-depth of the lure.

Beyond the aforementioned problems, a fisherman who uses the boatspeed-adjusting technique or the turning technique will not find successover time. This is because there is little chance of repeatability forthe given conditions. The fisherman/boat operator is not capable ofproviding a consistent “action” pattern to the lure. Further, over days,weeks, or even seasons, the fisherman's perspective of time in turns, orin throttle up/down times, will not be consistent. Thus, over time, theaforementioned techniques will not provide reliable “action” to the lureand reliable success in catching fish.

Accordingly, it is preferred to provide “action” to a fishing lure whentrolling that improves fishing consistency. Preferably, the fishermanwould be unburdened from constantly turning the boat or adjusting theboat's speed to provide the lure “action.” Thus, it is preferable toprovide “action” to the lure while the boat is moving at a constantspeed and without changing direction. It is further preferred to reducethe wear-and-tear on the boat's equipment. It is additionally preferredto provide for consistent “action” of the lure.

SUMMARY

Fishermen are provided with a system and method significantly advancingtrolling. A trolling system provides for control of a lure for depth andspeed. The control of which is localized to the trolling system at aplaner board, rather than requiring control of a boat or physicalcontrol of the rod to impart motion to the lure. Further, speed anddepth control are programmable, variable, and repeatable using a controlsystem and a brake. Having a trolling system unburdens a fisherman fromattempting to control the lure through the motion of the boat, and nowallows the fisherman to concentrate on other fishing strategies, whileat the same time, the lure is behaving a manner known to attract fishstrikes. Thus, the trolling system captures the critical aspects of luredepth and speed variation in a programmable system that does not requireintervention or attention of the fisherman.

A system is disclosed that includes a selectively positionable brake fora towed fishing body. Additionally, a system is disclosed that includesa speed control for a planer board. The planer board is used for fishingby being towed through water. Moreover, a method is disclosed includingpositioning a brake attached to a towed fishing body.

DETAILED DESCRIPTION

Referring now to the drawings, illustrative embodiments are shown indetail. Although the drawings represent the embodiments, the drawingsare not necessarily to scale and certain features may be exaggerated tobetter illustrate and explain an innovative aspect of an embodiment.Further, the embodiments described herein are not intended to beexhaustive or otherwise limit or restrict the invention to the preciseform and configuration shown in the drawings and disclosed in thefollowing detailed description.

FIG. 1 is a side perspective view of a first embodiment of a system fortrolling 30 having a brake 50 in a disengaged position. In general, aplaner board 40 is configured for attachment to a line for being pulledthrough water. Brake 50 is in a disengaged position where a shutter 11is in an open position, allowing for flow of water through a housing 13.Internal to planer board 40 is an actuator (not shown) that is connectedto shutter 11. A programmable control module 14 controls the actuator toselectively position shutter 11 in an engaged position and a disengagedposition (shown in FIG. 2). The operation and configuration of systemfor trolling 30 is described in detail herein.

FIG. 2 is a side perspective view of the embodiment of FIG. 1 having anengaged brake 50. As shown, engaged brake 50 is positioned tosubstantially interfere with water flow through housing 13 when planerboard 40 is towed through water. Control module 14 selectively positionsshutter 11 using an actuator to allow or block water flow throughhousing 13. In this way, the speed of planer board 40 is controlled, asis any lure or fishing tackle towed from planer board 40. Moreover, asdescribed in detail below, a lure is typically pulled by planer board 40and is given life-like “action” by the slowing down motion (when brake50 is engaged) and speeding up motion (when brake 50 is disengaged)provided by the actuation of brake 50.

The embodiments described herein reference a starboard-side planerboard. However, the systems and methods are equally applicable toport-side planer boards as well as in-line planer boards that are notbiased toward a side of the boat and generally run directly behind thetowing line. Moreover, the systems and methods described herein areapplicable to other types of towed fishing bodies such as downriggersand lures.

Referring now to FIG. 3, a top view of a trolling setup 20 is shownincluding a boat 22, a rod 24, a line 26, and a trolling system 30. Boat22 may be propelled through water in a travel direction 28 usingconventional motor systems such as an inboard motor(s), an outboardmotor(s), and a trolling motor(s). Rod 24 is selectively connected toboat 22 by rod holders (not shown). Line 26 is affixed at a first end 32to rod 24 (typically using a rod and reel setup) and at a second end 34to trolling system 30.

During the implementation of trolling setup 20, rod 24 is typicallytemporarily disconnected from boat 22 to allow a fisherman to attachtrolling system 30 to second end 34. Then, the fisherman may placetrolling system 30 in the water and may begin letting out line from thereel to position trolling system 30 at a desired nominal distance behindboat 22. The implementation procedure may be repeated for other trollingsystems 30 a, 30 b, and 30 c. When trolling setup 20 is complete, a lure36 is pulled through the water by a leader 26 a that is a furtherextension of line 26.

Now turning to FIGS. 4A and 4B, an embodiment of trolling system 30includes planer board 40 and brake 50. Planer board 40 further includesa top side 60, a bottom side 62, an inboard side 67, an outboard side69, a leading edge 64, a trailing edge 66, a bias portion 68, a pullingattachment point 70, and a lure attachment point 72. Pulling attachmentpoint 70 and lure attachment point 72 are shown as spring-clip typequick connects. However, other methods of line attachment for towing arealso contemplated. Brake 50 (explained in detail with respect to FIGS.5A-5C) is positioned at bottom side 62 of planer board 40 and isgenerally positioned underwater when in use.

Planer board 40 may be made of plastic material and preferably includesa buoyant portion such that planer board 40 is automatically oriented inthe water properly. As is known to those skilled in the art, planerboard 40 may also be constructed of wood or foam. Further, the balanceof planer board 40 is important so that, when towed, the board slicesthrough the water in an upright position.

Planer board 40 is attached to line 26 at pulling attachment point 70allowing boat 22 to pull planer board 40 through the water connected byline 26. Line 26 is further attached near trailing edge 66 at lureattachment point 72. An intermediate segment 26 b of line 26 is strungbetween pulling attachment point 70 and lure attachment point 72. Lure36 trails behind trolling system 30 by its connection with leader 26 a.(See FIG. 3). In general, pulling attachment point 70 and lureattachment point 72 may be configured as clips, pinchers, or otherconfigurations that do not allow slippage of line 26 therethrough.

FIG. 5 illustrates a perspective view of brake 50 including shutter 11,housing 13, and pivot points 46, 48. An axel may be placed between pivotpoints 46, 48 through shutter 11, or pivot points 46, 48 may be part ofshutter 11. Other embodiments may include pivot points 46, 48 as part ofhousing 13. Moreover, housing 13 may include holes or depressions forreceiving pivot points 46, 48. Housing 13 is generally box-shaped andincludes a channel 88 therethrough that allows for the placement ofshutter 11 within. For clarity, an upper portion of housing 13 is notshown that spans a first upper edge 42 and a second upper edge 44 (theupper portion of housing 13 is shown in FIG. 1). Housing 13 generallyprotects shutter 11 from damage. Channel 88 allows water to flow throughhousing 13 when towed in the water. Shutter 11, in this embodiment, is aflat plate. As shown, pivot points 46, 48 allow shutter 11 to rotatewithin housing 13.

Shutter 11 is an embodiment of a selectively positionable brake forplaner board 40. The selective positioning is derived from the movement,or in this embodiment, a rotation of shutter 11 as a moveable surface.Housing 13 includes an inlet 17 and an outlet 18 for water passingtherethrough. When brake 50 is engaged, shutter 11 is positioned suchthat water passage is blocked near to shutter 11. When brake 50 isdisengaged, shutter 11 is positioned such that water is allowed to flowpast. Although the embodiment shows a housing 13, brake 50 operateswithout housing 13. In the embodiments shown herein, housing 13 is usedto protect shutter 11 while not in use (e.g., when placed in storage orwhile being setup or handled).

In an embodiment, brake 50 is constructed of stainless steel. Thisallows brake 50 to also operate as ballast for planer board 40,assisting in maintaining planer board 40 upright in water. Housing 13may be constructed of sheet material that is folded or cut andsubsequently welded or bonded together to form housing 13.Alternatively, housing 13 may be constructed from a predetermined lengthof extruded material. Shutter 11 may be a cut or formed piece of sheetmaterial. The construction of housing 13 and/or shutter 11 of metalallows for a significant mass located near bottom side 62 of planerboard 40. Further, stainless steel is non-reactive in normal freshwaterbodies of water providing for minimal rust or other degradation.

In an alternative embodiment, the components of brake 50 may beconstructed of plastic. Indeed, the components may be molded components.However, brake 50 may also be constructed of materials, or combinationsof materials, that provide strength and environmental ruggedness.

FIG. 6A is a perspective cross-sectional view of brake 50 when engaged.Brake 50 is attached to bottom side 62 of planer board 40. With brake 50in an engaged position, shutter 11 is rotated about pivot points 46, 48to a closed position to substantially minimize channel 88, therebyblocking water flow through housing 13. In alternative embodiments,shutter 11 may completely close-off channel 88 through housing 13.Control module 14 is programmed to operate an actuator 210 that, in thisembodiment, rotates shutter 11 via a direct-drive shaft 52. A battery 54provides power for control module 14 and actuator 210. FIG. 6B isperspective cross-sectional view of brake 50 when disengaged. Whendisengaged, shutter 11 is rotated to an open position to substantiallymaximize channel 88 through housing 13, allowing for the free flow ofwater through housing 13.

FIGS. 7A and 7B illustrate the operation of brake 50 as trolling system30 is towed through water. It is understood that brake 50 is alsoapplicable to other types of towed fishing bodies. FIG. 7A illustrates across-section of brake 50 in an engaged position, e.g. where shutter 11blocks the water's path through housing 13. An entering current 100(shown by arrows) is provided by the motion of trolling system 30 as itis being pulled or towed through water. Shutter 11 substantially closesoff channel 88 and prevents entering current from passing through brake50. Thus, a resistive force is provided to trolling system 30 as it ispulled through water by blocking entering current 100. In thisembodiment, the resistive force of brake 50 is substantially against thepulling or towing force.

As shown in FIG. 7B, brake 50 may be disengaged by selectivelypositioning shutter 11 to an open position such that channel 88 ismaximized. Thus, entering current 100 is provided an unobstructed paththrough housing 13. In the open, or disengaged position, enteringcurrent 100 passes through channel 88 and is substantially undisturbedresulting in the flow of exit current 102. In allowing entering currentto be substantially undisturbed, the resistive force applied to trollingsystem 30 is minimized.

In this embodiment, brake 50 is positioned underwater and is locatedunder planer board 40 (see FIGS. 6A and 6B) to provide a laterally andlongitudinally balanced resistive force to planer board 40. However,alternative embodiments may include unbalanced configurations that mayprovide more resistive force to one of the sides 67, 69 or to leadingedge 64 or trailing edge 66 of planer board 40. Further, brake 50 may beconfigured to provide lift to raise planer board 40 higher in the water.Thus, when brake 50 is disengaged, planer board 40 is raised out of thewater and less resistive force is applied by the water to the body ofplaner board 40. Alternatively, brake 50 may be configured with apartial housing 13.

Referring now to FIGS. 8A and 8B, an alternative embodiment of trollingsystem 30 is shown. In this embodiment, brake 50 is provided as atwo-part balanced system, including shutters 106, 108 mounted on sides67, 69 on the lower portion of planer board 40. Thus, shutters 106, 108are substantially under water when planer board 40 is in use. Advantagesof a balanced setup of brake 50 include a straight pull through thewater where positioning of planer board 40 is determined by bias portion68 (shown in FIGS. 4A and 4B). However, the general towed direction ofplaner board 40 may be modified by adding an imbalance through theselective use of one side, or both sides, of brake 50 to steer planerboard 40 in the water (e.g., the opening of shutter 106 and the closingof shutter 108, or the opposite). Indeed, such a dual shutter setupallows for the braking and steering of planer board 40.

In this embodiment, an axel connects shutters 106, 108 and provides forselective rotation about pivot points 86, 87, 110, 112 to allow for theopening and closure of shutters 106, 108 and channel 88. The balancedconfiguration allows for a fisherman to selectively attach ballast tobottom side 62 to fine tune the riding position (e.g. the portion ofplaner board 40 under and above water) of trolling system 30. Further,the strength of brake 50 may be increased by a greater contact area withplaner board 40, thereby reducing the risk of breakage. Additionally,the balanced configuration allows for a modified riding position oftrolling system 30 on the water with shutters 106, 108 open (see FIG.8B) and closed (see FIG. 8A).

Now turning to FIG. 9, a controller system 200 is shown for trollingsystem 30. Controller system 200 is an embodiment of programmablecontrol module 14 shown in, for example, FIG. 1. Controller system 200includes a processor 202, a memory 204, a power system 206, inputs andoutputs 208, and an actuator 210. Processor 202 is a low powermicrocontroller having discrete inputs and outputs for interacting withthe other components of controller system 200. In this embodiment,processor 202 is an Atmel AVR® ATtiny15L microcontroller that operatesat low voltage and low power consumption. Processor 202 also includeson-board clock generation and on-board memory 204 in the form of RAM,FLASH, and EEPROM. Thus, external components are minimized.

In general, memory 204 includes both data memory and program memory foroperating processor 202. At least a portion of the data memory ispreferably stored in a non-volatile portion of memory such that the datamay be restored through a power cycle and/or after power system 206 isdisconnected. The uses of the non-volatile data memory are described indetail below with respect to FIGS. 21-29.

Power system 206 includes a charging port 212 and a voltage regulator214. Power system 206 includes rechargeable batteries (e.g.,nickel-cadmium, or lithium-ion, etc.). Further, it is advantageous toinclude the batteries in a “pack” arrangement so that easy replacementis possible. However, it is also advantageous to provide for the use ofnon-rechargeable batteries, such as alkaline batteries, in caserecharging is not convenient. Alternatively, non-rechargeable batteriesmay provide for a higher charge-density allowing for longer runs. Onesuch user of alkaline batteries is in critical situations where longerone-time-use is desired, such as in fishing tournaments. Additionally,regulator 214 is not necessary when the battery voltage is matched tothe operating range of processor 202.

In this embodiment, charging port 212 provides an external power sourcefor recharging of the batteries. The re-charging logic may be providedwithin power system 206, or may be controlled by processor 202. Chargingport 212 is embodied as a standard “barrel plug” and includes awaterproof boot such that water will not penetrate the electricalcomponents of controller system 200. Further, power system 206,specifically the batteries, may be enclosed in a separate water-tightarea away from processor 202. This is advantageous where replacement ofthe batteries is desired, but the processor and other components ofcontroller system 200 are not within the same water-tight area.

Inputs and outputs 208 provide for the programmability of controllersystem 200 and allow for feedback to the fisherman. In this embodiment,inputs and outputs 208 include an on/off pushbutton 220, a programmingpushbutton 222, an on/off indicator 224, and a program indicator 226.Here, pushbuttons 220, 222 are waterproof SPST-type pushbuttons and maybe exposed directly to the environment or may be covered by a waterproofplastic boot. Indicators 224, 226 are LED's, but may also be provided inother embodiments such as lamps or flash-type indicators. Pushbuttons220, 222 and indicators 224, 226 are electrically connected to processor202 and are, in general, controlled directly by processor 202 forreading inputs and activating outputs. The function of pushbuttons 220,222 and indicators 224, 226 are explained below in detail with respectto FIGS. 21-29.

Actuator 210 may be embodied as a servo-mechanism, a motor, or as alinear or rotary solenoid. However, actuator 210 may be embodied as anymechanism capable of movement when commanded. In some embodiments,described in detail below, actuator 210 is a servo having a rotaryoutput. Servo systems are known in the art and may include servos suchas a standard FUTABA® S3004. Linear and rotary solenoids are also knownin the art. Actuator 210 is operably connected to brake 50 and providesmotion to selectively provide resistive force to planer board 40. In theembodiments described herein with respect to FIGS. 10A and 10B, actuator210 selectively positions shutter 11. The operation of actuator 210 isdescribed in detail with respect to FIGS. 10A and 10B.

Generally, the actuators discussed herein are referred to aselectro-mechanical devices. Examples of such electro-mechanical devicesare geared or direct-drive motors, linear solenoids (e.g., pull type orpush/pull), latching solenoids, and rotary solenoids. However, othertypes of actuators are contemplated. For example, actuators can also bea non-electro-mechanical device. One type of actuator may be a gearedsystem powered by the movement of the towed fishing body (e.g., awater-wheel powered mechanical system). Such mechanical systems may alsoinclude spring or coil powered (wind-up type) mechanical motion devicesthat would not require batteries. Alternatively, other actuators arepossible, including combinations of the aforementioned types ofactuators.

Turning now to FIGS. 10A and 10B, the operation of trolling system 30 isdescribed in detail. A controller 240 and an actuator 242 are mounted totop side 60 of planer board 40 using screws, glue, or double-sided tape.Controller 240 is an embodiment of controller system 200 (shown in FIG.9) and programmable control module 14 (for example, shown in FIG. 1).Mounting controller 240 and actuator 242 on top side 60 allows them tobe substantially out of the water. Such an above water configuration ispreferred where water-resistant housings are used rather thanwater-proof housings.

Power system 206 may be mounted anywhere on the board, and may bepositioned to be balanced when trolling system 30 is in the water. Tothis end, the batteries (not shown) of power system 206 are mountedinternally near the bottom side 62 of planer board 40 and furtheroperate as ballast to maintain trolling system 30 upright in water (seealso FIG. 11A detailed description).

Actuator 242 includes an actuator arm 250 connected to the motion systemof actuator 242. Further, shutter 11 of brake 50 also has a shutter arm252 that rotates shutter 11 along pivot point 86. Actuator arm 250 andshutter arm 252 are operably connected by a connecting link 254. Thus,when actuator 242 is commanded to move by controller 240, connectinglink 254 moves shutter 11 via shutter arm 252. In this manner, whentrolling system 30 is pulled through the water by line 26, the flow ofwater through brake 50 may be controlled.

In operation, controller 240 selectively positions shutter 11 of brake50 to control water flow through brake 50. (See detailed descriptionwith respect to FIGS. 7A and 7B). As is illustrated in FIG. 10A, whenbrake 50 is engaged, shutter 11 is in a closed position and enteringcurrent 100 is not allowed to pass through housing 13 (e.g., enteringcurrent 100 enters housing 13 at inlet 17 but cannot exit at outlet 18).Thus, a resistive force, or drag, is introduced to planer board 40 bythe force of entering current 100 against shutter 11 when pulled throughwater. Alternatively, controller 240 may command actuator 242 todisengage brake 50 and open shutter 11 such that water flow, e.g.entering current 100, is allowed to enter housing 13 at inlet 17 andexit at outlet 18 (exiting current 102). Thus, drag is minimized.

As is illustrated in FIGS. 10A and 10B, actuator arm 250 and shutter arm252 are of similar lengths. However, arms 250, 252 may be of unevenlengths to maximize the force applied to shutter 11. Depending upon thespeed of boat 22 (see FIG. 3) and the water current, a predeterminedtorque is necessary to open and close shutter 11. In cases whereactuator 242 does not have enough direct torque to open and closeshutter 11, a mechanical advantage may be employed (because of thegear-head motor in the servo) by making actuator arm 250 of a longerlength. Additionally, the angles of rotation for actuator 242 may beadjusted using different length arms 250, 252. However, in the presentembodiment, arms 250, 252 are of the same length. Thus, when actuator242 turns ninety (90) degrees about an actuator pivot point 256, shutter90 will also turn ninety (90) degrees about pivot point 86. (See FIGS.10A and 10B).

Connecting link 254 is a length of stainless steel wire cut to a lengthapproximately equal to the distance between actuator pivot point 256 andpivot point 86. The length is chosen to facilitate the rotation ofshutter 11 with a ninety (90) degree rotation of actuator 242 where arms250, 252 are of equal length. Further, connecting link 254 is configuredhaving loops on both ends that connect with loops on arms 250, 252.However, alternative embodiments may have connecting link 254 rotablyattaching to arms 250, 252 using ball joints or other connectionconfigurations allowing for the movement of connecting link 254.

FIG. 11A illustrates a battery compartment 260 near bottom side 62 ofplaner board 40. Battery compartment 260 is sealed from water intrusionby a battery plug 262. Battery compartment 260 holds four (4) AA sizebatteries that connect in series and supply power to controller 11.Battery plug 262 is secured to planer board 40 by a threaded connection.Battery compartment 260 is shown near bottom side 62 of planer board 40such that the mass of the batteries (not shown) contained within batterycompartment 260 counteract the mass of controller 14 and actuator 242 ontop side 60 of planer board 40. Thus, the balance of the mass maintainsplaner board 40 in an upright position in the water. However, as will bedescribed in detail below, the placement of controller 14, actuator 242and battery compartment 260 are not critical to the balancing oftrolling system 30. This is because planer board 40 is configurable toinclude ballast (e.g., lead) and flotation (e.g., a floatation substancesuch as foam) at desired locations to ensure proper orientation in thewater.

FIG. 11B is atop plan view of battery plug 262 having a threaded portion270 and an o-ring 272. Threaded portion 270 makes a connection with athreaded inner portion of battery compartment 260. This threadedconnection holds battery plug 262 to planer board 40 as well as providesthe force necessary to compress o-ring 272. In addition to the threadedconnection, o-ring 272 provides a water-tight seal between batterycompartment 260 and battery plug 262. To replace batteries, a userunscrews battery plug 262 and removes the batteries. Once the batteriesare replaced, the user screws battery plug 262 with the necessary torqueto optimally compress o-ring 272. Those skilled in the art willunderstand the use of a compression limiter to prevent over-tighteningof o-ring 272.

FIG. 12A is an embodiment of trolling system 30, including a firstsolenoid 280, a second solenoid 282, and a plunger 284. As discussedherein, plunger 284 and other components of solenoids and/or motors maybe plastic coated to prevent corrosion that may interfere with theelectrical or mechanical properties of the actuators. Plunger 284further includes a pivot point 290 that connects to a linkage 292. Pivotpoint 290 allows linkage 292 to move with plunger 284 in a frontposition (illustrated in FIG. 12A) to a back position (illustrated inFIG. 12B). Linkage 292 connects to an arm 294 that rotates shutter 11through pivot point 86. In this embodiment, control module 14 and theactuator (embodied as first solenoid 280, second solenoid 282, andplunger 284) are located within planer board 40. The advantages of suchan arrangement include reduced susceptibility to damage from crush orimpact. Additionally, the balance of trolling system 30 is improvedwithout the use of ballast or additional floatation materials. Further,trolling system 30 is less likely to pick up foreign materials, such asweeds or branches, when pulled through the water because there are feweracute angles on the exposed surface of planer board 40.

In operation, the selective movement of shutter 11 provides for theengagement and disengagement of brake 50 acting against the water flowproximal to brake 50. Control module 14 selectively energizes andde-energizes first solenoid 280 or second solenoid 282 to positionplunger 284. When control module 14 desires to close shutter 11, firstsolenoid 280 is energized and second solenoid 282 is de-energized. Thus,plunger 284 will move toward and pass through first solenoid 280. (SeeFIG. 12A). When the opening motion of plunger 284 occurs, linkage 292pushes shutter 11 closed by moving arm 294.

When control module 14 desires to open shutter 11, first solenoid 280 isde-energized and second solenoid 282 is energized. Thus, plunger 284moves towards, and passes through, second solenoid 282. (See FIG. 12B).When the closing motion of plunger 284 occurs, linkage 292 pulls shutter11 open by moving arm 294.

Alternate embodiments include the possibility to selectively commandfirst solenoid 280 and second solenoid 282 such that an intermediateposition of shutter 11 is achieved. Control module 14 commands firstsolenoid 280 and second solenoid 282 using a pulse width modulationscheme to selectively position plunger 284 at various distances betweenfirst solenoid 280 and second solenoid 282. Therefore, by controllingthe position of plunger 284, a variable position of shutter 11 isachieved through the connection of linkage 292 and arm 294.

FIGS. 13A and 13B are side views of an embodiment of trolling system 30.Brake 50 is mounted to bottom side 62 of planer board 40 and includesshutter 11, housing 13, pivot points 86, 87, and an arm 390. A controlmodule 400 is mounted near top side 60 of planer board 40 and isconfigured to be housed substantially within planer board 40. Controlmodule 400 is a package containing a battery 402, controller 240, anactuator 404, a charging port 406, an on/off pushbutton 408, aprogramming pushbutton 410, a first indicator 412, and a secondindicator 414.

Control module 400 is configured as a snap-in module that facilitatesmanufacturing and repair. Thus, control module 400 may be builtseparately from the mechanical components of trolling system 30 andinstalled as a single part during production. The attachment methods forcontrol module 400 may include gluing, heat staking, screws, or “snaps”constructed into an injection molded planer board 40. Further, controlmodule 400 contains sealed areas, such as controller 240 and battery402, to avoid water intrusion and damage to sensitive components.

Charging port 406 is used to charge battery 402 when drained, or totop-off the charge when partially charged. Further, charging port 406includes a water-tight closure that includes an o-ring to prevent waterintrusion into control module 400. Charging port 406 includes a standardbarrel-type receptacle that preferably receives a 9-14 volt input. Thecharging source preferably is provided from boat 22, a vehicle (e.g., atruck), or a wall charger for use in a home. The charging voltage level,the charging current level, and the specific embodiment of thereceptacle may also be configured to receive charging systems as isknown in the art. However, the charging voltage and current are matchedto levels expected by the charging circuitry in control module 400.

Controller 240 (discussed in detail with respect to FIG. 9) is alsoprovided with inputs and outputs electrically connected to on/offpushbutton 408, programming pushbutton 410, first indicator 412, andsecond indicator 414. Pushbuttons 408 and 410 are SPST switches that arewaterproof for reliability. On/off pushbutton 408 turns control module400 on and off. Programming pushbutton 410 determines the delay timesfor brake 50. First indicator 412 and second indicator 414 are LED's andare used to indicate the status of trolling system 30. First indicator412, when lit, indicates that controller 240 is active and ready foroperation. Second indicator 414 indicates the programming status ofcontroller 240. The functions of the pushbuttons and indicators aredescribed in detail below with respect to FIGS. 18-26.

Actuator 404 is a solenoid constructed of a winding used to create amagnetic field within an air core as those skilled in the art willappreciate. Preferably, the coil is designed for three (3) voltoperation. The air core slidably receives a plunger 420 made ofpermeable metal. The steel or iron plunger 420 is attracted within thefield generated by actuator 404 when energized. Actuator 404 is alsoconfigured as a latching-type solenoid such that when the stroke ofplunger 420 is fully within the coil, plunger 420 latches in thisposition. Another stroke of plunger 420, provided through a momentaryactivation of the coil in actuator 404, unlatches plunger 420. Thelatching of plunger 420 may be by magnetic latching. A spring 422 thenpulls plunger 420 partially out of the air core of actuator 404. Anenergizing pulse of actuator 404 then pulls plunger 420 back to alatched position.

To effectuate movement of shutter 11, plunger 420 is connected to arm390 by a linkage 424. Linkage 424 is directly and rigidly connected toplunger 420 and moves linearly with the movement of plunger 420. Thus,as plunger 420 moves toward top side 60 of planer board 40, linkage 424also moves linearly in the same direction. Additionally, as spring 422pulls plunger 420 toward bottom side 62 (when plunger 420 is unlatchedby a pulse from actuator 404), linkage 424 is also pulled linearlytoward bottom side 62. By way of arm 390 that is connected to shutter11, the opening and closing of shutter 11 is provided by the linearmovement of plunger 420. By way of example, FIG. 13A shows shutter 11 ofbrake 50 in a closed position when plunger 420 is pulled to the maximumposition towards bottom side 62 by spring 422. Alternatively, FIG. 13Bshows shutter 11 in an open position when plunger 420 is pulled andlatched toward top side 60 when actuator 404 is energized. When in theopen position, plunger 420 is latched until another pulse to thesolenoid of actuator 404 occurs.

FIGS. 13A and 13B show linkage 424 connecting plunger 420 to arm 390within the body of planer board 40. Actuator 404, plunger 420, andlinkage 424 are mounted substantially midway between inboard side 67 andoutboard side 69. This arrangement provides for balance when planerboard 40 rides through water. FIG. 13B illustrates shutter 11 in an openposition. 13A illustrates shutter 11 in a closed position where plunger420 is fully pulled within actuator 404 and latched. Thus, linkage 424is also pulled towards top side 60 and arm 390 rotates shutter 11 to theclosed position. FIG. 13B illustrates shutter 11 in an open positionwhere plunger 420 is unlatched and is pulled towards bottom side 62 byspring 422 (shown in FIG. 13B). Thus, linkage 424 is also pulled towardsbottom side 62 and arm 390 rotates shutter 11 to the open position. InFIGS. 13A and 13B, note that arm 390 is placed near back side 66 ofplaner board 40 relative to shutter 11. The rear mount allows forreduced “snagging” of water-born objects, such as plants (e.g., seaweed)and twigs, and also provides for self-clearing when shutter 11 is openedsuch that water flow therethrough will wash away a snagged object.

FIG. 14 is a top plan view of trolling system 30 and a standard planerboard 504 when pulled by boat 22 in travel direction 28. In thisscenario, trolling system 30 is not used with brake 50 being variablycontrolled (e.g., trolling system 30 is turned off). When trollingsystem 30 is disabled, brake 50 may be disengaged (if not already soarranged) so that trolling system 30 behaves similarly to standardplaner board 504. Standard planer board 504 maintains a distance B whenpulled through water. Trolling system 30, when brake 50 is continuouslydisengaged, maintains a distance A when pulled through water.

FIGS. 15A and 15B illustrate the effects upon an un-flexed rod 24 a, anun-tensioned line 26 c, a flexed rod 24 b, and a tensioned line 26 d.When brake 50 is disengaged (e.g., shutter 11 is in an open position toprovide low resistance), the drag upon trolling system 30 is minimal.Therefore, there is a reduced, or normal, force from planer board 40 inthe water pulling on un-flexed rod 24 a. Due to the reduced forcerequired to pull trolling system 30, un-tensioned line 26 c is in anormal state of tension. Further, un-flexed rod 24 a is also in a normalstate where there is a reduced stress on un-flexed rod 24 a to pulltrolling system 30 through the water.

However, when brake 50 is engaged, (e.g., shutter 11 is in a closedposition to provide a high resistive force), significant additionalforce is required to pull trolling system 30 through the water. Thus,tensioned line 26 d is in a high-tension state and flexed rod 24 b isunder strain to pull trolling system 30 through the water.

In FIG. 15A, a distance D illustrates an un-flexed distance between theattachment point of rod 24 of boat 22 to the tip of rod 24.Additionally, un-tensioned line 26 c may exhibit line droop and isgenerally not under high-tension. FIG. 15B illustrates a flexed distanceE where a greater tension is placed on flexed rod 24 b due to theengagement of brake 50. Thus, the difference of un-flexed distance D andflexed distance E must require that trolling system 30 is at a greaterdistance behind boat 22 when brake 50 is engaged. Moreover, at leastduring the transition periods of rod-flex, the speed of trolling systemis controlled by brake 50. Further, the slack of line 26 is taken up,and also line 26 is stretched, providing that trolling system 30 is at agreater distance behind boat 22 when brake 50 is engaged.

FIG. 16 shows the variable positioning of trolling system 30. Boat 22pulls trolling system 30 in travel direction 28. A first position 500and a second position 502 are shown for trolling system 30. Boat 22 alsopulls standard planer board 504 for relative comparison. When brake 50is disengaged (e.g., in a reduced drag configuration) trolling system 30is at first position 500 and is a distance A behind boat 22. When brake50 is engaged (e.g., in a high drag configuration), trolling system 30is at second position 502 and is a distance C behind boat 22. Standardplaner board 504 is at a constant distance B behind boat 22 and is, inthis example, between first position 500 and second position 502.

Variable positioning of trolling system 30 is accomplished through theselective introduction of a resistive force, or drag, using brake 50. Tothis end, controller 240 moves actuator 242 to disengage or engage brake50 in a reduced drag or increased drag configuration respectively. Asshown in FIG. 15A, when brake 50 is disengaged (e.g., in a reduced dragconfiguration) un-flexed rod 24 a and un-tensioned line 26 c providethat trolling system 30 is closer to boat 22 as shown by first position500 and distance A. FIG. 15B shows the flexed rod 24 b and tensionedline 26 d when brake 50 is in a high drag configuration. Thus, trollingsystem 30 is at second position 502 and is a distance C behind boat 22.When brake 50 is periodically transitioned from a reduced dragconfiguration to a high drag configuration (e.g., brake 50 isperiodically disengaged and engaged), trolling system 30 moves betweenfirst position 500 and second position 502, relative to boat 22.Therefore, trolling system 30 is selectively positioned at distances Aand C behind boat 22. Moreover, the speed of trolling system 30 is alsocontrolled during the transitions between distances A and C.

Controller 14, in an embodiment, is configured to periodically positionbrake 50 in a low drag configuration and a high drag configuration toeffectuate the variable positioning of trolling system 30. Byselectively introducing drag to trolling system 30, the speed andposition of trolling system 30 and lure 36 is controlled by controller14. At first position 500, trolling system 30 is generally operating atthe same speed as boat 22. However, when brake 50 is in a high dragconfiguration, the speed of trolling system 30 is slowed such thattrolling system 30 moves from position A to position C behind boat 22.Likewise, when brake 50 is disengaged to a low drag position, trollingsystem 30 speeds up and achieves position A from position C.

For each distance A and C, a delay time (or dwell time) is programmablefor controller 14 such that the positioning and/or periodicity of thetrolling system 30 is controllable. Further, in circumstances such aswhen significant waves are present in the water, trolling system 30 maynot require variable speed and positioning (due to wave action on planerboard 40). Thus, controller 14 may be turned off and trolling system 30may be used as a standard planer board.

FIGS. 17A-17C show the effects of variable speed and variablepositioning of trolling system 30 on the positioning of lure 36 in thewater. A portion of planer board 40 is above a surface 528 of water. Aportion of planer board 40, including brake 50, is below surface 528.FIG. 17A illustrates trolling system 30 pulled through water at a steadystate with brake 50 in a reduced drag configuration. Entering current100 is generated by a pulling motion 520 of trolling system 30 throughthe water. In a reduced drag configuration, entering current 100 isallowed to pass through brake 50 allowing exit current 102 to flow outthe back. In this state, lure 36 is positioned a distance C behindtrolling system 30 and a depth A below surface 528. In thisconfiguration, lure 36 moves at a constant speed 530 and is at a firstposition 540.

Now turning to FIG. 17B, when brake 50 is in an increased dragconfiguration, entering current 100 is blocked by shutter 11 in brake50. Flexed rod 24 b now allows trolling system 30 to move more rearwardof boat 22 by at least the difference of distances D and E. Includingline tension (the difference between un-tensioned line 26 c andtensioned line 26 d), the distance of trolling system 30 behind boat 22is increased. As a result of the introduced restive force (e.g. drag),trolling system 30 decelerates along vector 522. Thus, the mass of lure36 drops in the water and positions lure 36 a closer distance D fromplaner board 40. Further, due to the repositioning, lure 36 is at asecond position 542 having a deeper depth B under surface 528. Themotion from the position of lure 36 in FIG. 17A to the position in FIG.17B is illustrated by vector 532.

Turning now to FIG. 17C, brake 50 is configured for low drag andentering current 100 is allowed to pass through brake 50. Thus, trollingsystem 30 accelerates along vector 524 and speeds up to substantiallythe same speed as boat 22. Rod 24 is in an un-flexed position 24 a andun-tensioned line 26 c allows for closer positioning of trolling system30 to boat 22. The position of lure 36 now transitions along vector 534back to the steady state first position 540 at distance C behindtrolling system 30 and depth A below surface 528. The actual distancefor first position 540 and second position 542 behind trolling system 30and depth below surface 528 is determined by several factors, includingthe length of leader 26 a and the properties of lure 36 itself (such asdrag and buoyancy).

By periodically configuring brake 50 for reduced drag and high drag, thespeed and position of trolling system 30 is controlled. Further, throughthe programmability of controller 240, the timing and distance iscontrollable. Indeed, where controller 240 and actuator 242 provide forintermediate positioning, any position between first position 500 andsecond position 502 is achievable. In general operation, trolling system30 provides selective positioning and/or periodic positioning of lure36.

The selective acceleration and deceleration and selective positioningfrom first position 540 to second position 542 provides for therealistic “action” of lure 36 in the water. It is known in the art offishing that a lure having “action” is more likely to entice a fish tostrike, and therefore, more fish are caught. By including the aspect ofvariable speed control and variable positioning in trolling system 30, atrolling setup is provided that allows boat 22 to continue at a steadystate through the water while still providing “action” to the lures.This allows for the fisherman to concentrate on other activities, aswell as reduces wear and tear on the components of boat 22. Further, theprogrammable features of trolling system 30 allow for precise andrepeatable action of lure 36.

FIG. 18 is a side view and depth chart of a floating crank-bait stylelure as pulled by trolling system 30 and alternatively, as pulled bystandard planer board 504. Trolling system 30, standard planer board504, and the lure are pulled by boat 22 in travel direction 28 at aconstant speed and direction. Under these conditions, standard planerboard 504 pulls the lure at a constant depth E under water 528, the pathof which is described by a constant depth line 600. The properties ofthe floating crank-bait style lure determine depth E and generallyinclude lure style, mass, buoyancy, length of line set-back (embodied asthe length of leader 26 a), line 26 diameter, and the trolling speed.Indeed, as is illustrated by constant depth line 600, the depth of thelure (determined primarily due to the length of leader 26 a) does notchange in speed or depth when pulled by standard planer board 504. Thus,no action is imparted to the lure.

When pulled through the water by trolling system 30, an action isimparted to the lure as shown by a varying depth line 602. Brake 50 isclosed at a first time 610 and the lure begins to slow down and rise inthe water as illustrated by an upward motion 612 to a depth F. Thisaction is imparted to the lure because there is reduced pulling forceprovided by trolling system 30 when brake 50 is closed. Due to thenature of floating crank-bait style lure, the inherent buoyancy of thelure provides that the lure will rise in the water when less pullingforce is applied. At a predetermined time, brake 50 opens at a secondtime 614. The lure then has increased pulling force applied by trollingsystem 30. The lure then darts forward and down to depth E in a downwardmotion 616 based on the characteristics of the lure and the setup(described above). As can be seen by varying depth line 602, the natureof trolling system 30 provides for a periodic action of the lure atdepths E and F under surface 528 of the water.

FIG. 19 is a side view and depth chart of a sinking-body-bait-style lureas pulled by trolling system 30 and alternatively as pulled by standardplaner board 504. Trolling system 30, standard planer board 504, and thelure are pulled by boat 22 in travel direction 28 at a constant speedand direction. Under these conditions, standard planer board 504 pullsthe lure at a constant depth G under water 528, the path of which isdescribed by constant depth line 600. The properties of thesinking-body-bait-style lure determine depth G and generally includelure style, mass, buoyancy, length of line set-back (embodied as thelength of leader 26 a), line 26 diameter, and the trolling speed.Indeed, as is illustrated by a constant depth line 620, the depth of thelure does not change in speed or depth when pulled by standard planerboard 504. Thus, no action is imparted to the lure.

When pulled through the water by trolling system 30, an action isimparted to the lure as shown by a varying depth line 622. Brake 50 isopened at a first time 630 and the lure darts forward and upward in thewater as illustrated by an upward motion 632 to depth G. This action isimparted to the lure because there is increased pulling force providedby trolling system 30 when brake 50 is opened. Due to the nature of thesinking-body-bait-style lure, the mass (and lack of buoyancy) causes thelure to fall in the water when reduced pulling force is applied and riseup when increased pulling force is applied. At a predetermined time,brake 50 closes at a second time 634. The lure then has reduced pullingforce applied by trolling system 30. The lure then slows and drops inthe water to depth H in a downward motion 636 based on thecharacteristics of the lure and the setup (described above). As can beseen by varying depth line 622, the nature of trolling system 30provides for a periodic action of the lure at depths G and H undersurface 528 of the water.

FIG. 20 is a side view and depth chart of acrawler-harness-with-a-snap-weight-type lure as pulled by trollingsystem 30 and alternatively, as pulled by standard planer board 504.Trolling system 30, standard planer board 504, and the lure are pulledby boat 22 in travel direction 28 at a constant speed and direction.Under these conditions, standard planer board 504 pulls the lure at aconstant depth I under water 528, the path of which is described by aconstant depth line 640. The properties of thecrawler-harness-with-a-snap-weight-type lure determine depth I andgenerally include lure style, mass, buoyancy, length of line set-back(embodied as the length of leader 26 a), line 26 diameter, and thetrolling speed. Indeed, as is illustrated by constant depth line 640,the depth of the lure does not change in speed or depth when pulled bystandard planer board 504. Thus, no action is imparted to the lure.

When pulled through the water by trolling system 30, an action isimparted to the lure as shown by a varying depth line 642. Brake 50 isopened at a first time 650 and the lure darts forward and upward in thewater as illustrated by an upward motion 652 to depth I. This action isimparted to the lure because there is increased pulling force providedby trolling system 30 when brake 50 is opened. Due to the nature of thecrawler-harness-with-a-snap-weight-type lure, the mass causes the lureto rise up when increased pulling force is applied and fall in the waterwhen reduced pulling force is applied. At a predetermined time, brake 50closes at a second time 654. The lure then has reduced pulling forceapplied by trolling system 30. The lure then slows and drops in thewater to depth J in a downward motion 656 based on the characteristicsof the lure and the setup (described above). As can be seen by varyingdepth line 642, the nature of trolling system 30 provides for a periodicaction of the lure at depths I and J under surface 528 of the water.

In this illustrative example, a longer time between first time 650 andsecond time 654 allows for the lure to maintain depth I for a dwellperiod 660 before further action is imparted by trolling system 30.Thus, the timing of opening and closing of brake 50 may be programmedfor fast action, slow action, and further provides for variable andprogrammable depths of the lure. Where brake 50 is programmed to openand close before depths I and J are achieved by the lure, trollingsystem 30 controls variable depth between the normal depths I and J asdetermined by the setup alone.

FIG. 21 is a flow diagram of the operation of the brake for the trollingsystem of FIG. 3. A control process 2400 begins at step 2402 where brake50 is disengaged. This allows for trolling system 30 to move forward intravel direction 28 with a minimum of resistance.

Next, at step 2404, an open delay is performed while brake 50 isdisengaged, allowing for planer board 40 to accelerate in traveldirection 28. Lure 36 also accelerates as the pulling force isincreased. The delay is variable and programmable. Thus, planer board 40may be allowed to accelerate to a steady state speed the same as boat22, or may be allowed to accelerate only a portion of time before planerboard 40 attains the speed of boat 22.

Next, at step 2406, brake 50 is engaged. At this time, planer board 40decelerates and increased tension is applied to line 26 and rod 24 bendsto a flexed position for flexed rod 24 b.

Next, at step 2408, a closed delay is performed while brake 50 isclosed, allowing for planer board 40 to decelerate. Lure 36 alsodecelerates as the pulling force is decreased. The process then repeatsas control proceeds to step 2402.

In general, the action imparted to lure 36 based on control process 2400is described in detail with respect to FIGS. 18-20. The motion impartedto planer board 40 is described in detail with respect to FIGS. 16-17C.Additionally, the mechanics of rod 24 and line 26 are described indetail with respect to FIGS. 15A and 15B. In this way, the speed andposition of planer board 40 and the speed and depth of lure 36 arecontrolled.

FIG. 22 is a flow diagram of the selection of variable timing of thebrake for the trolling system of FIG. 3. A delay selection process 2500begins at step 2502 where a fisherman selects a delay time for the openposition of brake 50.

Next, at step 2504, the fisherman selects a delay time for the closedposition of brake 50.

Next, at step 2506, the fisherman loads the selected delay times tocontroller system 200.

Next, at step 2508, trolling system 30 begins operation as described indetail with respect to control process 2400, which is described indetail with respect to FIG. 21.

Selection of delay times and the loading of the delay times areperformed through inputs/outputs 208 via on/off pushbutton 408 andprogramming pushbutton 410, which is described in detail with respect toFIGS. 9 and 13A. Additionally, feedback for the selected delays and theloading of the delays are provided by first indicator 412 and secondindicator 414 as a positive indication that the selection andprogramming functions were successful. Absent a fisherman's input,controller system 200 may automatically configure delay times based onknown delays providing a high probability of success for averagetrolling speeds and lure 36 types.

FIG. 23 is a flow diagram of the stored operation 2600 of the brakeusing stored parameters for the trolling system of FIG. 3. On power-up,controller system 200 begins operation by reading saved delay programsfrom memory 204 at step 2602.

Next, at step 2604, a fisherman may select a stored program using on/offpushbutton 408 and programming pushbutton 410 described in detail withrespect to FIGS. 9 and 13A.

Next, at step 2606, controller system 200 programs the selected open andclosed delays.

Next, at step 2608, trolling system 30 begins operation as described indetail with respect to control process 2400, which is described indetail with respect to FIG. 21.

The saved programs may include open and close delays known to be goodfor the region, or fishing conditions presented to the fisherman. Forexample, if the fisherman were at the same location the day earlier andexperimentally determined the optimum open and closed delays, thesedelays will likely perform similarly under the current conditions.However, if conditions have changed slightly, the previous days'settings at least provide a starting point for the fisherman. Afterdetermining the success of the prior days' delays, the fisherman mayadjust the delays to further refine the action of lure 36.

FIG. 24 is a flow diagram of the operation of water parameterconfiguration 2700 for the trolling system of FIG. 3. At step 2702, thecurrent water parameters are determined. This step may involve afisherman collecting information from local weather services (i.e.,water temperature, barometric pressure, etc.) as well as on-siteinformation such as water temperature, salinity, pH, cloudiness, etc.Additionally, controller system 200 may include sensors for theseconditions that allows for automatic detection of the water conditions.

At step 2704, the fisherman may then consult a chart that includesinformation compiled regarding the programming of open and closed delaysfor these specific conditions. Further, given the automatic datacollection of controller system 200, a program may automatically beselected for the given water conditions.

At step 2706, the open and closed delays are programmed to trollingsystem 30 by the fisherman, or automatically by controller system 200.

At step 2708, trolling system 30 begins operation as described in detailwith respect to control process 2400, which is described in detail withrespect to FIG. 21.

FIG. 25 is a flow diagram of the saved parameter feature 2800 of thebrake for the trolling system of FIG. 3. At step 2802, controller system200 powers on.

Next, at step 2804, saved parameters are loaded from memory 204. Thesaved parameters may include the delay times for engagement anddisengagement of brake 50. The saves parameters may also includepredetermined profiles for the time delays for brake 50. Moreover, thelast programmed parameters that were saved may be loaded. Alternatively,selection of a fisherman's favorite settings may be loaded.

Next, at step 2806, trolling system 30 begins operation as described indetail with respect to control process 2400, which is described indetail with respect to FIG. 21.

Next, at step 2808, a request for powering off is determined bycontroller system 200. The request for powering off may come from on/offpushbutton 408 made by the fisherman when the trolling sequence iscomplete. Additionally, a request for powering off may be determined bycontroller system 200 itself under fault conditions or when power system206 is deemed to be in a low-power state (e.g., the battery is too lowto continue operation).

Next, at step 2810, controller system 200 saves the open and closeddelays to memory 204. Such a saving operation is performed by saving thedelay parameters, and statistical information, if available, to anon-volatile memory such as an EEPROM or to FLASH memory.

FIG. 26 is a flow diagram of the selective positioning 2900 of the brakehaving a strike detector for the trolling system of FIG. 3. In step2902, trolling system 30 is performing under normal operation asdescribed in detail with respect to control process 2400, which isdescribed in detail with respect to FIG. 21.

Next, in step 2904, controller system 200 determines if a strike hasbeen detected. Strike detection may be provided by a strain gaugeattached to leader 26 a and provides controller system 200 with anindication if a significant force is applied to lure 36. This allowscontroller system 200 to infer whether a fish is on. Additionally, aspring may be used in-line with leader 26 a with a magnet attachedthereto. When a fish is on, the spring will be stretched and the magnetwill move to a position detectable by a hall-effect device thatindicates a strike. In either case, if controller system 200 does notdetect a strike, control proceeds to step 2902. If a strike is detected,control proceeds to step 2906.

In step 2906, having detected a strike, controller system 200 opensbrake 50 such that the fisherman will have less resistance when pullingin the fish. If brake 50 were closed, or remains in normal operation,resistive force (drag) is increased which will make reeling in the fishmore difficult for the fisherman. Additionally, depending upon the sizeof the fish, line 26 may be excessively stretched, or in a worst casemay break, due to the increased drag. Thus, controller system 200 opensbrake 50 when a strike is detected. Control then proceeds to step 2908.

In step 2908, controller system 200 maintains brake 50 in a low-dragconfiguration until a reset is performed by the fisherman. Thus, at thisstage, the fisherman is reeling in the fish and when landed, thefisherman resets trolling system 30 allowing for continued fishing. Whena reset is detected by controller system 200, through the pushing ofon/off pushbutton 408, control proceeds to step 2902 where normaloperation resumes.

FIG. 27 is a flow diagram of a strike indicator 3000 for the trollingsystem of FIG. 3. In step 3002, trolling system 30 is performing undernormal operation as described in detail with respect to control process2400, which is described in detail with respect to FIG. 21.

Next, in step 3004, trolling system 30 determines if a strike has beendetected (described in detail with respect to FIG. 26). If a strike hasnot been detected, control proceeds back to step 3002 where normaloperation continues. If a strike is detected, control proceeds to step3006.

In step 3006, a strike indicator is activated. The strike indicator maybe a noise-making device (e.g., a piezo-electric alarm) or a lightindicator (e.g., a narrow beam LED configured to target boat 22, or awide beam LED or light source configured to be seen from a plurality ofdirections). The strike indicator then signals the fisherman that astrike has occurred and that the fish should be reeled in. Further,actions such as the placement of brake 50 in a reduced drag state may beaccomplished to further assist the fisherman as described in detail withrespect to FIG. 26. Control the proceeds to step 3008.

In step 3008, controller system 200 maintains the strike indicator in anon-state. When a reset is detected by controller system 200, through thepushing of on/off pushbutton 408, control proceeds to step 3002 wherenormal operation resumes.

FIG. 28 is a flow diagram of remote signal commanding 3100 for thetrolling system of FIG. 3. In step 3102, trolling system 30 isperforming under normal operation as described in detail with respect tocontrol process 2400, which is described in detail with respect to FIG.21.

Next in step 3104, controller system 200 is polling for a remote signal.The remote signal may be configured as a radio-type signal that isavailable to be received by an additional receiver within controllersystem 200. For example, but not limited to, a 300-400 MHz system may beused (similar to remote keyless entry systems for vehicles) to controltrolling system 30 remotely. Signals from boat 22, sent by thefisherman, may include updates to the programming sequence or timingdelays to brake 50. Such updates may come remotely to reduce the amountof time necessary to reel in trolling system 30 and reprogram. Further,where numerous trolling systems 30 are in use, the programs may beupdated in real time without requiring hands-on programming. Whencontroller system 200 detects a remote signal, control proceeds to step3106. Otherwise, normal operation continues as control proceeds to step3102.

In step 3106, controller system 200 performs the remote command aftervalidating the command. The remote command may be to open brake 50 untila reset, change the open and closed programming delays, etc. When theremote command is performed, control proceeds to step 3108.

In step 3108, controller system 200 determines whether or not to returnto normal operation. If a return to normal operation is warranted, e.g.,after new programming has been performed such as the loading of new openand closed delay times, control proceeds to step 3102. Else, controlremains at step 3108 until such time as a return to normal operation hasbeen determined.

FIG. 29 is a flow diagram of a rough-sea mode 3200 where the brake ispositioned in a low-drag configuration when the controller module isturned off. Rough-sea mode 3200 begins at step 3202.

Next, at step 3204, trolling system 30 is performing under normaloperation as described in detail with respect to control process 2400,which is described in detail with respect to FIG. 21.

Next, at step 3206, a request to turn off is determined by controllersystem 200. The request for powering off may come from on/off pushbutton408 made by the fisherman

Next, at step 3208, controller system 200 configures brake 50 for arough-sea position that is where brake 50 is configured for a reduceddrag position.

Next, at step 3210, controller system 200 turns off with brake 50 in areduced drag configuration.

CONCLUSION

The saying “10% of the fishermen catch 90% of the fish” rings true.Better fishermen on average catch significantly more fish due to theirknowledge, experience, skill, and attention to detail. Improvements introlling skills and apparatuses have continuously allowed for bettersuccess than simply dragging a lure around in the water. Improvedfishing systems for boats allow for quiet trolling, global positioningsystems (GPS) allowing pinpointing of fishing locations and patterns, aswell as autopilot systems to take the fishermen to the best locationsare available. As systems have improved, fishermen now have boatsavailable to get them to the appropriate location, electronics to locatefish, mapping of underwater structures, detection of thermoclines,depth, and water temperatures. All of these systems provide betterinformation to fishermen to further improve the location and catching offish.

Additionally, it is known in the art to spread lures away from the boatthrough the use of planer boards. Further, it is known that fish willattack a lure where the lure provides realistic “action.” Thus,fishermen have attempted to control the depth of the lure through theactions of taking the boat in and out of gear, as well as steering inzigzag patterns. However, the techniques for providing action to a lureare complex, not easy to repeat consistently, take time andconcentration away from the fishermen, as well as being generallyabusive to the boat's drive system.

Hence, trolling system 30 provides for an improved trolling techniquefor controlling the critical aspects of speed and action of lure 36.Rather than controlling a standard planer board using boat movement,trolling system 30 allows for precise control of the lure from theplaner board itself. Additionally, trolling system 30 allows for preciseand repeatable control of lure 36.

Fishermen are now provided with an apparatus and method significantlyadvancing trolling techniques. Trolling system 30 provides for controlof lure 36 depth and speed. The control of which is localized totrolling system 30 at planer board 40, rather than controlling boat 22to impart motion to lure 36. Further, speed and depth control areprogrammable, variable, and repeatable through control of brake 50.Having trolling system 30 unburdens a fisherman from attempting tocontrol lure 36 through the motion of the boat, and now allows thefisherman to concentrate on other fishing strategies, while lure 36 isbehaving in a manner known to, attract fish strikes. Thus, trollingsystem 30 captures the critical aspects of lure 36 depth and speed in aprogrammable system that does not require intervention by the fisherman.

Trolling system 30 provides the opportunity to cause any style of lureto have action in the water by changing speeds. Further, most lures willalso adjust depths depending upon their configuration and buoyancy, orlack thereof. Trolling system 30 also provides variable timing optionsto make the speed and depth changes of lure 36 more or less dramatic inproviding the fish strike attracting action. Such action is known byfisherman to attract strikes. Thus, the fisherman will typically hold arod in their hands and “pump” the rod and lure in an attempt to attractfish. Thus, action is imparted to a lure by way of a tugging motion bythe fisherman from the boat. Such an action requires the attention ofthe fisherman and it is not possible to “pump” multiple rods at the sametime. Additionally, by requiring a fisherman to constantly “pump” therod, the fisherman may become tired from the constant physical workoutrequirements.

The operation of trolling system 30 is very much indeed an advancementin fishing technology. In an example of use, a fisherman picks up aplaner board (or other towed fishing body) and programs the delay timesthrough pushbuttons. Then, the planer board loads programmed delays andbegins operating brake 50. Next, a low light condition LED may be turnedon so that the fisherman can see the action of the boards in the water.Then the board is attached to line 26 and placed in the water where itis pulled by boat 22.

Trolling system 30 then performs a rhythmic speed-up and slow-downaction that is controlled by the timing determined by the fisherman. Thefisherman then can determine the “fish on” condition by a faster thannormal slow down action when brake 50 is closed, or a slower than normaladvance when brake 50 is opened. Once it is determined a fish is on thehook, the fish is fought in the same was as using a standard planerboard. Further, trolling system 30 is configured such that a fishermanmay handle the planer boards in the same manner as a standard planerboard because the mechanical and control systems are totally enclosedwithin planer board 40.

Additionally, planer board 40 of trolling system 30 allows for the“reading of the board” and “reading of the rod tips” to determine whatis going on with lure 36 underwater. A preferred rod has thecharacteristic of good strength and having a sensitive tip. When brake50 is in an increased drag state, the rod and rod top will be “loaded”more than when brake 50 is in a low drag state. The loading of rod 24increases the rate of acceleration of planer board 40 when brake 50transitions from a high drag configuration to a low drag configuration(e.g., when brake 50 disengages and a lurching forward of planer board40 and lure 36 occurs). When this transition occurs, the lure rapidlystarts forward which is the preferred motion to attract a fish strike.Additionally, a strike indicator may be used for smaller fish that maynot significantly influence the motion of trolling system 30, and thus,are more difficult to detect by the fisherman watching rod 24 and planerboard 40.

The system and method for trolling disclosed herein includes a planerboard as an example of a towed fishing body. However, other types oftowed fishing bodies are also appropriate for the application of thesystems and methods disclosed. For example, the towed fishing body maybe a downrigger or a lure, among other towed fishing bodies.

While the brake embodiments described herein are generally rotatableplanar surfaces, other embodiments and equivalents are alsocontemplated. For example, the brake may include surfaces that mayselectively extend directly outward from the towed fishing body. Inanother embodiment, panels may hingedly swing away from the towedfishing body to interrupt water flow. Alternatively, a normallyfree-rotating water wheel may be selectively stopped to brake a towedfishing body. The brake may also be, for example, a perforated surfacethat is moved into the water to create turbulence and reduce thehydrodynamic efficiency of the towed fishing body. Additionally, thebrake may be embodied as a mechanism attached in-line with the towingline so as to selectively adjust the distance from a boat to the towedfishing body. Generally, the brake may be embodied as an apparatus orfeature used to slow or stop the towed fishing body when under tow. Suchslowing or stopping may be relative to the tow mechanism (e.g., a boat),the water, or both.

As discussed herein with regard to towing, the embodiments typicallyshow a boat having a rod. The boat's movement in the water tows thefishing body by a fishing line. However, the towing mechanism may beconsidered the boat, the rod, the line, and/or a rod holder (e.g., arod, a rod holder, a reel, etc.) Additionally, the towing may beaccomplished by a powered craft or another body that is pulled or towed.Moreover, the towing is not necessarily the boat itself. An intermediatetowed body having the towed fishing body disclosed herein is alsoconsidered the towing entity.

With regard to the engagement and disengagement of the brake disclosedherein, the timing may be programmable by a user, for example, bypushbutton. Alternatively, the timing may be read from a memorylocation, or determined by sensors that adapt the timing to waterconditions. In other embodiment, timing may be determined by switches.When a mechanical and/or electro-mechanical actuator system is used,timing may be determined by mechanical programmability in selectingdifferent gearing for example, for a geared motor-driven actuator.Moreover, if the power is derived from movement of the towed fishingbody in the water, the size of a water wheel or rotary arm dependingtherefrom may be adjusted to provide timing. The timing may be periodic(e.g., a repetitious timing having a single period, or having a sequenceof periods). In another embodiment, a pre-programmed profile that is innon-volatile memory may be used. Alternatively, a timing algorithm maybe used to determine the engagement and disengagement of the brake. Ifperiodicity is not required, for example where conditions lendthemselves to random motion to improve the life-like effects of thelure, a specialized timing may be appropriate (for example, aslow-slow-fast-slow-fast that repeats). Long sequences may also bedefined that recycle after completion. Alternatively, a fisherman coulduse a long sequence that does not repeat (e.g., the sequence stops aftercompletion). This would allow the fisherman to complete the programmedprofile and change profiles if no strikes occur during the operation ofthe profile.

The aforementioned advantages and operation of trolling system 30 aremaintained by controller system 200. Thus, these improvements,programmability, and advantages to trolling are now available throughliterally the touch of a button. In order to power controller system200, there is a battery pack having a water tight charging port foreasily re-charging the system. The battery charging can be accomplishedon board boat 22, in a vehicle with a 12 volt system, or indoors with a12 volt AD/DC adapter. The entire electronic control will bewater-proofed such that water intrusion will not be a concern. Further,an eight (8) hour operation without requiring a re-charging cycle ispreferred so that a fisherman does not have the burden to discontinuetrolling operations unnecessarily.
